I've been looking on Audiogon and other places and noticed some misrepresented tube amplifiers. A 5U4/5AR4 based power supply in a tube amplifier can produce around 100 watts maximum output. An amplifier with one of these can provide up to 35 watts/channel at the very most. (AKA: Dynaco ST-70) I have seen claims on some amps with a single rectifier tube producing 50- 80 watts per channel. That's not happening! More current can be obtained by ganging up tube rectifiers.
